2. Service Eligibility Check
Before enquiring our services, it is recommended to ensure the best fit. Please double-check and confirm that a repair or resize is required, as frequent resizing may compromise the strength and integrity of your ring or bangle, particularly for jewellery with gemstones, engraving, or delicate details.
Wear at least a Month
We recommend you to wear your jewellery for at least one month before resizing to allow your finger/wrist to adjust naturally.
Observe Comfort
Observe comfort under varying conditions — temperature changes, activities, and daily wear can all affect how a jewellery feels.
